Enhanced tier
Premises or events where 800 or more people may reasonably be expected. Requires procedures plus additional measures and documentation.
The enhanced tier covers qualifying premises and events where 800 or more individuals may reasonably be expected at the same time. On top of the four public protection procedures, enhanced premises must put in place public protection measures, keep a document setting them out and provide it to the SIA, and (where the responsible person is an organisation) name a senior individual.
A few Schedule 1 uses — such as places of worship and certain education premises — remain in the standard tier even above 800.
Who it affects: Large venues, stadiums, big clubs and qualifying events expecting 800+.
